Ship built with Twin Towers steel in maiden voyage

The USS New York, a new battleship built with steel from the World Trade Center, sailed into New York harbour today on its maiden voyage and delivered a 21-gun salute near Ground Zero.

The $1 billion US Navy assault vessel, whose bow includes 7.5 tonnes of steel recycled from the 2001 terror attack, will be officially commissioned in its namesake city on Saturday.

Rescue workers and families of those killed in the attack gathered on the Manhattan waterfront to watch the 684ft warship glide up the Hudson River past the World Trade Center site with its sailors standing at attention on the deck.
